Organic Glass Bowl – Attributed to Royal Leerdam (Possibly Gerard Thomassen, “Serica” Series), Netherlands, circa 1990
Description:
A striking sculptural glass bowl in насыщенный emerald green, organically transitioning into clear glass at the base—an elegant study in weight, balance, and fluidity. The form appears almost molten, as if captured mid-pour: a soft, asymmetrical lip resting on a compact cylindrical foot, creating a dynamic tension between mass and lift.
The glass itself possesses a remarkable optical depth. Light travels through the saturated green body and disperses into the clear base, producing a luminous, almost aquatic effect. This interplay between color density and transparency is a defining characteristic of late 20th-century Dutch glass design.

About the Designer (Attributed)
This piece is attributed to Gerard Thomassen, a Dutch glass designer associated with the Leerdam tradition and active in the late 20th century. Thomassen’s work—particularly in the Serica series (circa 1990)—explores soft, biomorphic forms combined with rich, saturated color fields. His approach reflects a shift from strict modernist geometry toward a more expressive, almost sensual material language.
While definitive attribution cannot be confirmed without signature or catalog reference, the form, coloration, and technical execution align closely with known Leerdam production and Thomassen’s design vocabulary.
Design Context
Produced in the cultural afterglow of Dutch modernism, this object reflects the post-industrial evolution of the Leerdam glassworks, where designers began to reintroduce gesture, asymmetry, and material expressiveness into a historically rational design tradition.
In contrast to earlier functionalist clarity, works like this embrace:
Organic asymmetry over strict geometry
Color as spatial depth rather than surface decoration
Glass as sculptural mass, not just vessel
The result is a piece that sits between studio glass and industrial production, embodying the late 20th-century European shift toward more tactile, emotionally resonant design objects.
What for:
Ideal as a sculptural centerpiece or collector’s object. Works beautifully in minimalist interiors or alongside Scandinavian and postmodern glass. Particularly effective in natural light, where its color gradient becomes fully expressive.
